. The vertical siding tort-base .flashing 21. is pref -erablyL a x exible-fwaterproofed fabricf such as.; 55

saturated cotton drilling sanded to enhance its appearance and durability. The fabric siding 21 may be formed in any desired length, ranging from short lengths coextensive with the flashing sheets to a single continuous length of the length of the wall.

rIhe vertical siding or base flashing 21 has formed therewith a metal attaching and locking strip 22 in order that the siding may be readily attached to the through-wall flashing 18. Advantageously the strip 22 includes a fabric-gripping portion 23, Which may be formed by reversely bending the metal so as to clinch the fabric 21 between the sides thereof, and a lock portion 24 for ready locking engagement with the protruding portion of the flashing sheet 18. The locking portion is of bendable sheet metal, a portion of which is preferably bent to provide a flange 25 adapted to be positioned over the marginal flange 20 of the flashing and folded in between the portions 19 and 20 of the flashing as they are folded and pressed together. Preferably the fabric-gripping portion 23 and the lock portion 24 of the attaching strip 22 are laterally oiset, as at 26, so that the outer face of the gripping portion 23 will be in line with lthe outer face of the portion 19 of the flashing when the parts are assembled, and the fabric siding will lie flush with the wall as shown in Fig. 1.

As in the case of my prior patent, the flexible siding or base flashing is preferably of woven cotton drilling saturated with asphalt and having coatings of asphalt on both sides thereof, thus providing a durable waterproof siding that may be overlapped with the roofing material 27 in a manner as illustrated in Fig. 1.

In using my improved seepage protector the mason installs the through-wall ilashing 18 in the parapet Wall during the construction of the wall in such a way that the marginal edge portions 19' and 20 extend beyond the face of the wall. Thereafter when the roofer is ready to lay the roof 27, he may readily attach the flexible waterproof siding 21 to the flashing by merely inserting the flange portion 25 over the flange 20 of the flashing and then bending the two together and toward the wall so as to provide a lock joint. As stated above, the siding may be in short lengths coextensive with the lengths of the flashing or may be in a single length coextensive with the length of the kwall and as it is in perfect condition at the timeit is-applied to the face of the Wall, itmay 'bereadily mopped with cementitious material to the roofing composition 27, producing a highly satisfactory sheathing of pleasing appearance.

Having described one embodiment of my invention but Without intending to limit myself thereto, what I claim and desire to secure by Letters Patent is:

1. A seepage protector, for masonry walls and the like, the combination of a 'through-wall flashing extending through said wall and adapted to be embedded in a layer of mortar of said wall, a portion of said ashing sheet extending beyond said wall, and a flexible waterproof sheet adapted to be attached to said protruding edge portion of the through-wall flashing and sheet metal attaching means secured to said fabric and having a portion readily bendable into interlocking engagement with the protruding edges of said flashing.

2. In a seepage protector for masonry walls and the like, the combination of a sheet of metal flashing extending through said wall from side to side and for embedding horizontally in a layer of mortar, a flexible waterproof siding for overlying a vertical portion of said Wall and a portion of the roof, and means for attaching said siding to said flashing sheet comprising a metal attaching strip having a portion clamped to said fabric and another portion adaptable to be bent into interlocking engagement with the ilashing.

3. In a seepage protector for masonry Walls and the like, the combination of a series of through-wall flashings of sheet metal embedded horizontally in said wall, said sheets when in assembled relation in said wall providing a continuous sheet metal Waterproof flashing from side to side and through a length of said wall, and a separate single length of exible waterproof siding adapted to overlie a vertical face of said Wall throughout the length of said assembled flashing sheets, and means for attaching said length of flexible siding to said flashing sheets.
